Phosphorite - Wikipedia
For use in the stone fertilizer industry, beneficiated rock phosphate must be concentrated to levels of at least 28% phosphorus pentoxide (P 2 O 5), although most marketed grades of phosphate rock are 30% or more. It must also have reasonable amounts of calcium carbonate (5%), and <4% combined iron and aluminium oxides.
